Different varieties of angles exist in nature, and each one of them carries much importance in our everyday lives.
You are watching: An angle whose measure is 90
For example, architects and engineers usage angles when developing machines, buildings, roads, and also bridges.
In sports, athletes use angles to boost their performance. For example, a human being must spin through the disk in ~ a specific angle to throw it far in quick put. In soccer, you must use a specific angle to pass the round to the next player.
Carpenters and also artisans also use angles to fabricate objects such together sofas, tables, chairs, pails, etc. Artists usage angles to map out portraits and paintings. Fashion designers also use angle to come with certain with the best outfits. For these reasons, that is, therefore, important we discover the different types of angles.
(To go v the simple explanation the angles, you have the right to consult the ahead article, “Angles.”)
Different varieties of Angles
Angles space classified based on:MagnitudeRotation
Classification the angles based on their magnitude
There are seven varieties of angles based on their degree measurement. They include:Zero AnglesAcute AnglesRight AnglesObtuse AnglesStraight AnglesReflex AnglesComplete Angle– Zero Angle
A zero angle (0°) is one angle formed when both the angle’s arms are at the exact same position.
Classification of angle on the communication of rotation
Based ~ above the direction the rotation, angles can be classified right into two categories, namely;Positive AnglesNegative Angles
Positive angles space the varieties of angle whose measurements are bring away in a counterclockwise direction native the base.
Negative angles are measured in a clockwise direction native the base.
Other types of angles
Apart native the above discussed angles, there room other types of angles well-known as pair angles. They are called pair angles since they appear in bag to show a particular property. This are:Adjacent angles have actually the exact same vertex and arm.Complementary angles: Pair angle that include up come 90º.Supplementary angles: Pair angles whose amount of angle is same to 180º.Vertically the contrary Angles. Vertically the opposite angles are equal.Alternate internal Angles: alternative interior angles room pair angles created when a line intersects two parallel lines. Alternative interior angle are always equal to every other.Alternate Exterior Angles: Alternate exterior angles are merely vertical angle of the alternative interior angles. Alternating exterior angles room equivalent.Corresponding Angles: Corresponding angles space pair angles created when a heat intersects a pair the parallel lines. Corresponding angles are likewise equal to each other.

We saw a quick overview of the different varieties of angles. Next, we will watch the detailed write-ups on the most common species of angles (Complementary Angles, Supplementary Angles, etc.).
